4 None range:10 C to 40 ULTRASONIC FLOW DETECTOR ELECTRICAL WARNINGM isuse of this equipment and inappropriate electrical connections will createa shock appears to be simple connections to other equipment can put the patient and/or the operator atrisk of electrical shock. FOLLOW THE MANUAL INSTRUCTIONS ON THE USE OF THISEQUIPMENT. Avoid use involving electrical contact with other equipment. We assume no responsibilityfor misuse of our following is a guide to avoiding common potential hazards, this is NOT comprehensive. Alwaysseek the advice of a qualified Bio-engineer BEFORE making any electrical WHILE THE BATTERY IS BEING CHARGED IT IS DISCONNECTED FROM THE the charging circuit is active.

5 The Doppler won't work. This is a safety feature to preventpossible electrical shock to the battery charger must comply with the relevant national requirements ( EN60601-1:1990+A1:1993+A2:1995). The battery charging input circuitry must not be modified or altered in the equipment is not intended to allow operation on a patient while being charged and anymodification altering this will no longer comply with the tested NOT operate this instrument from other than its own self-contained CONNECTING TO A HI-FI OR INTERCOM SYSTEM: A medical-grade isolation transformer orcompletely isolated battery operation is the safest means of connecting HI-FI or intercom qualified technician or Bio-engineer should review all proposed OPERATION IN THE PRESENCE OF FLAMMABLE MATERIALS OR HIGH OXYGENCONCENTRATIONS: The possibility of explosion or fire always exists when this equipment isused in such an PATIENT BURNS.

6 In surgery these may occur through the probe when the Doppler is grounded(perhaps through an pole) and the electrocautery backplate has inadvertently not beenconnected. To protect against this ensure the cautery ground plate is on and only suspend theDoppler with an WARNING: This equipment should not be used with a defibrillator. SAFETY IS YOUR RESPONSIBILITY. IF IN DOUBT, SEEK EXPERT ULTRASONIC FLOW DETECTORM odel 811-B Operating ManualM0811-B, DESCRIPTIONOFF/ONThis switch turns the instrument off and POWER lamp will go on when theunit is turned on.

7 This lamp will blink ifthe battery needs charging. Although itwill operate for a few more hours, it shouldbe recharged as soon as JACKThe external battery charger plugs intothis jack. The charger must also beplugged into an appropriate alternatingcurrent outlet. The charger should supply16 V ac, 50-60 cycle at 250 battery is charging if the lamp bythe charger jack is illuminated. Whilethe battery is being charged it isdisconnected from the Doppler, whichmeans the Doppler won't work. Only thecharging circuit is active. This is a safetyfeature to prevent possible electrical shockto the battery cannot be recommend you put this unit oncharge at the end of every work day.

8 Youwill get longer, more reliable servicefrom the battery. Leaving the batterydischarged for days will shorten the lifeof the battery. You can expect a life oftwo to three years for the battery withnormal service and you believe the battery is getting weak,keep the volume low or use headphonesto get the maximum Doppler operatingtime before recharging or replacing knob controls the JACKWhen the optional stereo headphones areplugged in the speaker is disconnected, sothe sound is heard only through theheadphones. You always hear more,especially when you are checking weakflow or veins, through low MHZ PROBE JACKSThe probe is connected to two jacks.

9 Itdoesn't matter which side of the probeis connected to which jack. Theinstrument is marked with the frequencynumber of the Doppler ( ). The probeyou use must match this number. Thefrequency is engraved on the probebody. When ordering new probes, besure to order this instrument can be used with thestandard 10 mm diameter pencil probe,the skinny pencil probe ( mm ), theinfant flat and the adult flat instrument is designed only forvascular work, not obstetrical ULTRASONIC FLOW DETECTORTHE DOPPLER EFFECTIn vascular testing the Doppler effect describes the change in frequency that occurs when a transmittedenergy reflects from a moving formula describes the Doppler phenomenon: 2 FtV (COS ) CWhere.

10 F = The difference between Doppler probe frequency transmitted and the frequency = Two times the transmitting frequency of the Doppler = Velocity of insonated object (red blood cells). (theta) = The angle of incidence between the ultrasound beam and the blood = A constant which is equal to the velocity of ultrasound in tissue (1540 m/sec).The formula appears intimidating but its principle is easy. It merely states that if you direct a soundbeam at a moving object (here the Doppler ultrasound beam points at moving blood cells) thatobject s movement alters the frequency of the reflected sound beam.
